IMPROVEMENT IN BEER-COOLERS.

Specification -forming Beit known that I, ANTHONY PFUND, of the city,county, and State of New York, have invented a new and usefulImprovement in Coolers for Beer and other Liquids; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and u se thesame, reference being had to the accompanying drawing forming part ofthis specification, in which drawing- Figure 1 represents a longitudinalvertical section of my invention. Fig. 2 is a transverse verticalsection of the same. Fig. 3 is a horizontal section of the same. Fig. 4is a longitudinal vertical section of a modification of the same. Fig. 5is a transverse section thereof. Fig. 6 is a transverse section ofanother modification of the same.

This invention relates to a cooler for liquids, which consistsessentially of a closed tank made of sheet metal, or other good`conductor of heat, and placed in a vat, through which passes a constantstream of cold water, the water being first conducted into a chamberwhich is formed in the lower part of said vat, and from which extendpipes through the closed tank, either in a vertical or in a horizontalor inclined position, so that the liquid contained in said tank israpidly cooled by coming in contact with cold surfaces of thewaterpipes, and with the cold walls of the tank. The cold-water pipeswhich extend through the closed tank are arranged in groups, which aredistributed in such a manner that access can be had between them for thepurpose of cleaning the tank.

In the drawing, the letter A designates a tank which is made ot'sheet-copper, or other good conductor ot' heat, and which is entirelyclosed, and which is provided with one or two man-holes, a, throughwhich access can be had to its interior. When the tank is in actionthese man-holes may be open or closed. Said tank is situated in a vat,B, made of sheet metal, or any other suitable material, and under thetankis formed a chamber, (l, which communicates, by means of a pipe, b,with a reservoir, D, containing cold water. Through the tank A extends aseries of pipes, c, which part of Letters Patent No. 140,073, dated June17, 1873; application led June 6,

are open at both ends, and which may be situated in a vertical position,as shown in Figs. 1, 2, and 3, or in an inclined position, as shown inFigs. 4t, 5, and 6. When said pipes are in a vertical position theirlower ends communicate directly with the water-chamber C, so that thewater admitted to said chamber passes up through the pipes, and thiswater, after runnin gover the tank A, fills the annular space al betweenthe walls of the tank and those of the vat. From the upper part of thisspace extends a pipe, c, through which the water is allowed to' run off,so that a constant stream of water can be made to pass through thechamber C, the pipes c, and the annular space d. From the pipe c extendsa branch pipe, f, into a chamber, g, formed in the upper part of the vatB. This chamber is open at the top, and its inner wall is lower than theoutside wall of the vat, so that the water which accumulates in said vatwill overflow into the chamber, whence it can be drawn off through thepipes f and e. By this arrangement the Y hot water which accumulates inthe top ofthe vat B can be made to run off uniformly, and

the cooling operation can be effected with economy in water. From thebottom of the vat B extends a pipe, It, which communicates with thewaste-pipe c, and which serves to empty said vat whenever it may bedesired.

The water-supply pipe b communicates with the vat B by branch pipes t'j, situated at different levels, so that cold water may be injected intosaid vat at different points. From the bottom of the tank A extends apipe, 7c, through which the contents of said tank are discharged. Whenthe cooling-pipes c are arranged in an inclined position, as shown inFig. 4, horizontal partitions m m are placed in the annular space dwhich surrounds the tank A, so that the water which is admitted to thechamber G is compelled to circulate through the pipes c in a zigzagcourse. The pipes c are arranged in groups, either in the manner shownin Fig. 3, or in the manner shown in Figs. 5 and 6, so that room is leftbetween the severa-1 groups for a man to move about, and that easyaccess can be had to all parts ofthe tank for the purpose of cleaning.The walls of my tank A can be made very thin, since the same are exposedto a uniform pressure of liquid from the inside and from the outside,and the thinner these walls can be made the better is the cooling eectof the Water or other cooling medium surrounding the tank. When mycooler is constructed as shown in Fig. 6 the tank A may be leftuncovered.

What I do claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of a tank, A, in a vat, B, which is provided with acold-Water chainber, C, from which extend pipes c through the tank A,said tank being surrounded by an annular Water-space, d, substantiallyas herein shown and described.

2. The arrangement of the cooling-pipes c, which pass through the closedtank A in groups so situated that access can be had to all parts of theinterior of the tank, substantially as set forth.

This specification signed by me this 24th day of May, 1873.
